Amid a flurry of new construction at SpaceX’s Boca Chica facilities, technicians have begun to install thruster pods on Starhopper in anticipation of the prototype’s first untethered flights.

According to CEO Elon Musk, Starhopper’s “untethered hover tests” will begin with just one Raptor engine installed, potentially allowing hops to restart within the next few weeks. SpaceX is currently testing Raptor SN03 (and possibly SN02) a few hundred miles north in McGregor, Texas, just a few hours’ drive south once the engine is deemed flight-ready. Meanwhile, Starhopper itself needs a considerable amount of new hardware before it can begin Raptor-powered flight testing.

A Falcon Raptor-powered Starship

Purely from a visible perspective, the most important component Starhopper is missing is a way to control its attitude and remain stable while under Raptor power, particularly critical for hovering. Enter the aptly-named attitude control system (ACS), essentially a pod of omnidirectional thrusters. SpaceX already happens to have its own extremely mature ACS proven over nearly two dozen successful Falcon 9 and Heavy booster landings, as well as every Falcon upper stage that has ever flown. SpaceX’s ACS is based on powerful nitrogen gas thrusters, known for their white puffs during Falcon 9 booster recovery and landing operations.

On May 6th and 7th, SpaceX began to install what looked like Falcon ACS pods on Starhopper. Curiously, of the two pairs of thrusters now installed, half appear to be taken directly off of older mothballed Falcon 9 boosters, while the other two seem to have been acquired from a Falcon 9 Block 5 rocket. The latter pods may very well have come from Falcon 9 B1050, the booster that unintentionally landed in the Atlantic Ocean last December.

Based on the asymmetric location of the first two pod groups, Starhopper’s ACS will probably use a tripod layout. Additionally, the reason for the thruster pairs – versus Falcon 9’s single pods – is likely simple: Starhopper is far heavier than a Falcon booster. To get the same level of control authority, SpaceX is thus pairing pods together to double the functional strength of Starhopper’s ACS.

This leads smoothly to the installation of two (likely soon to be three) new composite-overwrapped pressure vessels (COPVs). Starhopper already has two COPVs installed on the outside of its upper tank dome, now effectively confirmed to be helium containers needed to pressurize the vehicle’s methane and oxygen tanks. Based on the fact that Starhopper’s new ACS pods appear to have come straight from Falcon boosters, it’s safe to say that the 2 (or 3) new COPVs will supply the hopper’s thrusters with gaseous nitrogen.

The Ugly Starshipling

In general, this is just the latest chapter in the book of the oddity that is Starhopper. With helium tank pressurization and nitrogen ACS thrusters taken straight from Falcon 9, a major facet of SpaceX’s Mars architecture is entirely missing from the prototype. Known as autogenous pressurization, BFR was meant to use gasified versions of its onboard liquid oxygen and methane to pressurize its propellant tanks. In a similar vein, BFR was expected to integrated the same propellant into its ACS. Simply put, helium is simply out of the question if SpaceX wants to realize its reusable Mars transport architecture. Mars does have a minute quantity of nitrogen available in its already very thin atmosphere, but extracting hundreds or thousands of kilograms is impractical in the near-term, particularly if the first Starship have to carry all of their extraction equipment from Earth.

In January, Musk noted that methane/oxygen RCS thrusters were no longer baselined on Starship/Super Heavy. It’s unclear if the “cold gas” referred to will be nitrogen on the final design.

Although Musk has seemingly confirmed that Starship and Super Heavy will use ACS thrusters more akin to the Falcon family’s cold nitrogen gas pods, he did also confirm that autogenous pressurization would be a part of even the earliest iterations of the rocket. The move from carbon fiber to steel tanks likely made a major difference, as carbon composites have extremely limited heat resistance.

Without autogenous pressurization and propellant tanks closer to the thickness of orbit-capable Starships, Starhopper is really more of a mobile test stand for Raptor than anything else. The ungainly vehicle also offers SpaceX engineers an opportunity to test Starship/Super Heavy avionics in flight conditions, particularly with respect to controlling a real Raptor engine on the fly.

Pending the arrival and installation of its lone Raptor engine, Starhopper will likely be ready to return to hop testing before the end of May. (NASASpaceflight – bocachicagal)

Analyst: Elon Musk’s $1 trillion Tesla pay deal modest against robot market potential

Jonas highlighted Tesla’s longer-term ambitions in robotics as a key factor in his assessment.

Morgan Stanley analyst Adam Jonas, one of Wall Street’s most ardent Tesla (NASDAQ:TSLA) bulls today, has described Elon Musk’s newly proposed $1 trillion performance-based compensation package as a “good deal” for investors. 

In a note shared this week, Jonas argued that the package helps align the interests of Musk and Tesla’s minority shareholders, despite its shockingly high headline number.

Future market opportunities

Jonas highlighted Tesla’s longer-term ambitions in robotics as a key factor in his assessment. “Yes, a trillion bucks is a big number, but (it) is rather modest compared to the size of the market opportunity,” Jonas wrote. He added that the humanoid robot market could ultimately surpass the size of today’s global labor market “by a significant multiple.”

“We have entertained scenarios where the humanoid robot market can exceed the size of today’s global labor market… by a significant multiple,” Jonas wrote, as shared on X by Tesla watcher Sawyer Merritt.

The analyst likened the arrival of AI-powered robotics to the transformative effect of electricity, noting that “contemplating future global GDP before AI robots is like contemplating global GDP before electricity.” The Morgan Stanley analyst’s insights align with the idea that as much as 80% of Tesla’s future valuation could be tied to its Optimus humanoid robot program.

Elon Musk’s pay package

Tesla’s board has tied Elon Musk’s proposed compensation package to some of the most ambitious targets in corporate history. The 2025 CEO Performance Award requires the automaker’s valuation to soar from roughly $1.1 trillion today to $8.5 trillion over the next decade, a level that would make Tesla the most valuable company in existence.

The plan also demands a leap in Tesla’s operating profit, from $17 billion in 2024 to $400 billion annually. It also ties the CEO’s compensation to a number of product milestones, including the delivery of 20 million vehicles in total, 10 million active Full Self-Driving subscriptions, 1 million Tesla Bots, and 1 million Robotaxis in operation. Tesla’s board emphasized that Musk’s leadership was fundamental to achieving such ambitious goals, with Chair Robyn Denholm noting the award would align the CEO’s incentives with long-term shareholder value.

Tesla posted 14,300 insurance registrations in China during the week of September 1–7, a 14.4% increase from the previous week’s 12,500 units. 

The figure marks Tesla’s highest weekly performance so far this quarter so far, despite the company’s year-over-year figures still being below 2024’s numbers.

Weekly registrations

The week’s registrations broke down to 5,000 Model 3s and 8,400 Model Ys, including the first 900 units of the newly launched Model Y L variant, as per estimates from industry watchers. On a quarterly basis, Tesla China is tracking 41.3% growth compared to the previous quarter, which bodes well for the company’s results this Q3 2025.

For the month of August, Tesla sold 57,152 vehicles in China, down 9.93% from the same period in 2024 but up 40.7% from July’s 40,617 units, according to the China Passenger Car Association (CPCA). Year-to-date, Tesla’s China sales are 7.2% lower compared to the previous year.

Model Y L first deliveries

The week ending September 7 was the first week that included the newly released Model Y L, a six-seat extended wheelbase version of the company’s best-selling all-electric crossover. Industry watchers estimate that last week, the first 900 units of the Model Y L have been registered, though this number is expected to increase in the coming weeks as deliveries of the vehicle hit their pace.

Citing information from a Tesla store in Beijing, Chinese media outlet Cailianshe stated that the Model Y L has been seeing a lot of interest among car buyers. “(The Model Y L) is selling very well. Since its launch, 120,000 orders have been received, with nearly 10,000 orders placed every day. The first batch of customers began receiving deliveries in the past two days,” a Tesla representative stated.

Tesla has introduced MultiPass, a new feature that allows owners to use their Tesla account to charge at non-Tesla charging stations. 

The service launched this week in the Netherlands, giving drivers the ability to find chargers, start sessions, and view charging history directly within the Tesla app.

Streamlining third-party charging

With MultiPass, Tesla owners can activate charging either through the Tesla app or by using their existing Tesla key card. This eliminates the need for separate accounts or additional cards from third-party networks. Tesla Charging highlighted the convenience of managing charging sessions in one location in a post on X, while Max de Zegher, Tesla’s Director of Charging for North America, emphasized that the update removes unnecessary friction.

“Nobody likes creating more accounts with payment details and passwords. For charging, this can even mean needing a third-party charging card mailed to your house. Starting in the Netherlands today, your Tesla App and your existing (!) Tesla keycard can start charging at third-party chargers. We’ll expand this to more countries quickly if customers love it. To make ownership effortless, the Tesla App should really be the only thing you need,” the Tesla executive wrote in a post on X.

Third-party payments and a familiar name

Tesla owners could pay for their third-party charging session with their Tesla accounts, as per the electric vehicle maker on its official website. Payments are drafted from users’ default payment method in the Tesla App, though charging costs will still vary depending on the third-party charger that is used.

Interestingly, the MultiPass name also echoes a pop culture reference. In the 1997 sci-fi film The Fifth Element, Leeloo Dallas-505 carried a futuristic “Multipass” smart card that functioned as her ID, passport, and ticket to space travel. Her accented repetition of “Multipass!” became one of the film’s most memorable lines, and it highlighted the card’s all-in-one convenience.

Tesla has not provided a timeline for Multipass’ U.S. rollout, though the service could become an important addition to the growing but often fragmented landscape of DC fast charging.
